[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.13.11.3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johannes Berg <johannes.berg@xxxxxxxxx>

commit 115b943a6ea12656088fa1ff6634c0d30815e55b upstream.

Jouni reported that when doing off-channel transmissions mixed
with on-channel transmissions, the on-channel ones ended up on
the off-channel in some cases.

The reason for that is that during the refactoring of the off-
channel code, I lost the part that stopped all activity and as
a consequence the on-channel frames (including data frames)
were no longer queued but would be transmitted on the temporary
channel.

Fix this by simply restoring the lost activity stop call.
